I have a table with products- One of the fields is product price. Once a month I get a new price list in Excel format from our parent company consisting of product number and the new price for each product. I convert this list into a a separate access table and run an update query which changes the old price to the new price for each product in the product table. How ever sometimes the price list contains new products which are not registered in my access table. That means I have to add them do my database manually. I was wondering if there is some way I can write the query so that it notifies me which product numbers that are new (i.e does not have an entery in the access table) so that I don't have to manually compare the two lists every time?
